Question

Well, i’m using regex to replace all white spaces to commas but there’s a white space at the end and i don’t know how to make the regex not replace him

What I have

25DEL 38DEL A73G

JS

 var valor = $("#mapaArquivos option:selected").val().replace(/\s+/g, ", ");

Output

25DEL, 38DEL, A73G,

Right Output

25DEL, 38DEL, A73G

Thanks for the help anyway!

Answer 1

Trim the value before applying regex. this way there will be no trailing or leading spaces

var valor = jQuery.trim($("#mapaArquivos option:selected").val())
                  .replace(/\s+/g, ", ");
